4. DISK ACCESS lamp

If the OS supports a power-saving mode, the green lamp flashes while the

server is in this power-saving mode. Pressing the POWER switch places the

server back in the normal mode.

6. DISK lamps

Each hard disk drive has a DISK lamp on its front panel. (1) in below figure

Figure 5: Disk lamp

Lights green: power is supplied to the hard disk drive.

Blinks green: the hard disk drive is being accessed.

Lights amber: the hard disk drive is defective in the RAID System

configuration.

Note: While hard disk drives are in a RAID System configuration (RAID1/

RAID5, RAID6, RAID10, or RAID50), a single failed hard disk drive does

not affect the operation of the server.

However, we recommend you replace the failed hard disk drive and auto-

rebuild (reconfigure) the hard disk drives as soon as possible. (You can hot-

swap such a failed hard disk drive.)

Blinks amber: during the data rebuild operation; when the defective hard disk

drive is replaced with a new one in the RAID System configuration.

Blinks green/amber: the hard disk drive is being rebuilt (this status is not a

failure).

Off: when the rebuild is terminated normally. The LED goes on amber if the

rebuild fails.

Caution: To abort a rebuild, power off the server. In such a case, restart the

server, hot-swap the failed hard disk drive, and restart rebuilding. Observe

the following notes to use the auto-rebuild feature.

• Do not power off the server. If the server is powered off before

rebuilding hard disk drives, the auto-rebuild feature will not start.
